The present invention relates to improve ments in hand nailing implement and has for an object to provide an implement more particularly useful in' connection with the f nailing of shoes in which a magazine is provided for maintaining great quantities of these nails and with mechanism for feeding these nails and driving the same into theshoe rapidly and expeditiously.

39 Another object of the invention lies in providing an improved hand nailing implement in which the magazine may be replenished with nails with great facility and in which the nails are fed singly from the magazine 15 to the nail punch.

it further object of the invention is to provide'an improved tool of this character in which a clinching operation is had upon the nail. I i I m With the foregoing and other objects in view, the invention will be more fully described hereinafter, and will be more particularly pointed out in the claims appended 3 hereto.

Figure 9 is a fragmentary longitudinal section of the lower part of the implement simi- VOV lar to Figure 2 but with the nail feeding device in a subsequent position, and

Figure 10 is a side view of the improved nail employed.

Referring more particularly to the drawings, 10 designates a base, which as shown in Figure 9 is provided with a channel 11 to re- '55 ceive the nail 12.

The nail employed is preferably of the headless type, having both ends beveled. The nail 12 is adapted to be SUSDGWlQ'Cl in the channel 11 above the lower or discharge end 60 of such channel. as by a spring pressed ball 13 proyecting a short distance into the channel and urged thereinto as by a coil spring 14:. The ball and spring are contained in a recess in the base piece 10 which opens through the side of such base piece and is normally closed by a screw cap 15 which may be removed to give access to the interior part. The base 10 is preferably provided with the incurved side wall to permit the tip of the device to be placed 70 close to the shoe sole or to any other part into which the nails are to be driven and considerable clearance is thus given the device.

The upper end portion of the base 10 is provided with an upstanding flange 16 providing an enclosed space at the upper end of such base piece for receiving the foot 17 at the bottom of the lower magazine section 18.

The magazine is shown more particularly in Figure 5, and the foot 17 thereof is provid ed with a recessed or cut away portion 19 to receive therethrough a slide 20 which act; as a nail feeding device from the magazine to the base channel 11. k

The slide 20 is provided with an opening 21 of substantially the same diameter as the nail 12 and this opening is adapted to re ter with the nail delivery slot 22 in the it e zine section 18. as shown in Figure 2. A coil 0 spring 23 is adapted to retain thc slide 20 in this initial position illustrated in Figure 2; and a push button 24 connected to the slide and projecting exteriorly 01: the implement provides means whereby the slide may be pushed over to the position illustrated iirFigure 9 in which the opening 21 is brought into alignment with the channel 11 whereby the nail, 12 may descend until checked by ball 18.

The slide 20 is confined in place as to its ends by the flange 16 ofthe base and as to its sides by the shoe or foot 17. The slide 20 is also provided with alarger opening which is normally above the channel 11 of the base as shown in Figure 2. This large opening 25 accommodates the plunger pin 26. The plunger pin is of a diameter to snugly fit thechannel 11. The plunger pin 26 is provided with a head 2'? having a threaded shank 28 screwed into a complemental socket in the lower end of the plunger 29. In this manner the plunger pin 26 may be removed and re placed from time to time. A coil spring 30 surrounding the plunger 29 acts to elevate the plunger and the plunger pin 26 to substantially the-position shown in Figures 2 and 3. V

The plunger 29 eXten ds upwardly above the enclosed parts of the device and'is adapted to receive-at its upper end ananv1l piece 31 for receiving blows from a-hamineror other;

appropriate tool. As shown'in Figure 3, the anvil piece 31 is preferably detachably .con-

nected with the plunger as by a screw threaded joint indicated'at 32 which will enablethe' removal and replacement of the anvil piece as the same becomes worn from repeated hammer blows. The upper end of the coil spring30 isadapted to take against a shoulder 33 on the plunger 29. The lower end of the coil spring 30 takes against ashou-lder 34 on a guide sleeve or bushing 35 which surrounds the plunger and a portion of the plunger rod. The head 27 and the lower end of the plunger are adapted to slide snugly in thelower portion of the guide-sleeve ,35 by which the movements of these parts is properly directed. As shown in Figures 3 and .65 the upper portion of the plunger is provided with a pin 36 having ends extendingat both 2 sides laterally beyond the plunger and fitted to slide in slots 37 in the upper portion of the guide sleeve 35. This pin supplements the lower portion of the guide'sleeve so that the plunger has a bearing at two remote points "F in the guide sleeve and lateral movement or wobbling of the plunger is avoided.

A cap 38 is fittedover the plunger and providedwith a threaded flange 39adapted to screw into the upper magazine section 40.

The cap 38 takes against the guide sleeve and holds the same down upon the shoulders 41 and 42 in the lower magazine section 18. The guide sleeve 35 also fits snugly into-the in-, terior of the lower portion of the upper magazine section whereby to retain the same in place.

'azine is closed. The lower end of the jacket other, .lIlQ received against a blank portion of 43 fits against a shoulder 45 upon the upper magazine section '40. This shoulder 45 is carried by an enlarged band portion 46011 the upper magazine section which acts to space the jacket from the magazine walls. A casing 47 extends about the lower magazine section 18 and the lower portion otthe upper magazine section 40 concealing the,jo int between the same and also partially confining the hopper 48 at the top ofthe nail delivery slot The hopper 48, as more particularly shown in Figure 5, is provided with downwardly convergent walls leading to the upper end of the nail slot 22, the arrangement being such that thenails will beidefliyered totheslot only on end whereby they will lie in the slot in the 1112111161 shown in Figure 9 and {thus insure their delivery to the slide andwto the base. a 1

The casin g 47ris-fixed to the lower magazine section 18 as by-the use of screws 49. The casing 47, :at itsupper end is'rotata bly connected with the upperrmfagazine section '40 as by the use of set screws .50avhich'engage throughslots 51 in the casing 4 7. A'.li p 52 on thecasing is adapted-to close a mouth 53 otthe magazine. 1 The lip is shown in the closed position in Figure l.

Screws or other fastenings 54 are let in through the foot 17 and engage in the base 10 for holding these parts removably together.

'In operation, the magazine is filled with nails of the type shown in Figure 9 preterably firstrotating the casing 47 with reference @to the upper magazine section whereby the lip :52 will Ievpose the month 53 of the magazine, The implement being inverted, nails may be poured in through the opening 53 until the magazine is properly filled. Then before righting the implement, the casing 47 is'rotated back to original position so that the month ofthe magazine is closed by the lip 52. VVhe-n' the magazine is then stood upright, the nails will fall into-the hopper 48, the'wal-ls of which willdirect such nails down intothe slot 22-where the nails'will be upended and will rest endtoend upon one an- 1 the lowermost nail in the slot 22bethe slide20 until the spring 23 shifts the slide back to the position shown in Figure 2 where the opening 21 is in position to receive a nail 1-2. The upper end of the'opening 12 is bev eled in order to guide the next uppermost nail out of the device should the end thereof tend to project into the opening 21 and interfere with the movement of the slide 20.

When the slide 20 is pushed over to theposition show-ninFigure 9. the nail 12 will descend into the channel 11 and against-the ball 13 which will prevent it from dropping through the base and being lost until it is properly applied to the shoe and the plunger driven down as by striking with a hammer or mallet. When the plunger is driven down, the plunger pin 26 enters through the channel 11 and drives the nail 12 downwardly, the ball 13 yielding to permit passage of same.

The nail is not only driven into the shoe but it is also clinched by the action of the plunger pin. The coil spring 30 will restore the plunger and plunger pin to the upper position immediately following the blow.

Referring more particularly to Figure 10,

the improved nail12 is shown having the pointed ends 60 and 61 offset to relatively 0pposite sides of the nail. The nail ends are sloping or beveled in opposite directions as 15 indicated at 62 and 63 and, when driven into the sole, the nail ends are adapted to clinch over in opposite directions as indicated by the dotted lines.

It is obvious that various changes and modifications may be made in the details of construction and design of the above specifically described embodiment of this invention without departing from the spirit thereof, such changes and modifications being restricted only by the scope of the following claims.
